Writing position

(File pointer)

● The writing position (file pointer) is specified in hexadecimal format in bytes.

● The file pointer setting is available only when the writing position specification mode1 or

mode 2 is specified.

● After the writing process into the file, the position of the end of written data is stored at the

writing position (file pointer). If the writing operation is performed again in this state, the next

data will be written.

● In case of the writing position specification mode 1, data is written in the file from the writing

position (file pointer) counted from the head of the file.

● In case of the writing position specification mode 2, data is written in the file from the writing

position (file pointer) counted from the end of the file.

● In the new file mode, data is always written from the head of a file. The writing position (file

pointer) after the writing process is not stored.

● In the add mode, data is always written from the end of a file. The writing position (file

pointer) after the writing process is not stored.

● The writing position is specified by one byte.

Example of processing (csv format file)

● Five pieces (five words) of unsigned 16-bit integer data are read from the area starting with

device DT2, and the data pieces are written in CSV format into the file "\abc\data1.csv" in the

SD memory card in new file mode.

● A blank line is inserted in the data through zero suppression, and a comma (2Ch) is inserted
